State volcanologists from the Philippine Institute of Volcanology and Seismology (PHIVOLCS) have observed ongoing volcanic activity at Mayon Volcano in Albay, including the effusion of lava and active lava flows in areas such as the Basud, Bonga, and Misi gullies over the past 24 hours. The agency also recorded several volcanic earthquakes, numerous rockfall and pyroclastic density current signals, and a visible crater glow that can be seen without equipment. Additionally, the volcano emitted nearly 3,900 tonnes of sulfur dioxide in one day, and signs of ground swelling were detected.
PHIVOLCS maintains Alert Level 3 (intensified unrest/magmatic unrest) for Mayon and has reiterated that people should avoid entering the 6‑kilometer Permanent Danger Zone or flying close to the volcano. Potential hazards include further lava flows, rockfalls, landslides, pyroclastic currents, moderate explosions, and lahars during heavy rainfall.
